WINAICO launches patented micro-crack preventing HeatCap technology at PV Taiwan

WINAICO launches patented micro-crack preventing HeatCap technology, and the highest power density 300 W and 230 W mono crystalline PV modules at PV Taiwan 2014

Taipei, Taiwan, 22.10.2014 – WINAICO, Taiwan's largest PV module manufacturer, launches patented HeatCap technology at PV Taiwan 2014. HeatCap improves the reliability of silicon based solar cells, and protect them from micro-cracks induced by external stresses, such as handling errors and wind stresses. WINAICO's high efficiency module with HeatCap technology was recently awarded the Taiwan Excellent PV Award by the Bureau of Energy. Also on display at WINAICO's booth are the world's first PERC-based 300 W WSP-300M6 (60-cell) and 230 W WST-230M6 (48-cell) high efficiency modules. WINAICO's 280 W, WSP-280M6, all-black module demonstrates the perfect combination of high energy output and beautiful design, suitable for any Residential application without compromising the roof aesthetics.

WINAICO's internal evaluation showed evidences of HeatCap improving the ultimate stress a silicon solar cell can withstand before breaking up to 18.12%. WINAICO also worked with Taiwan's leading research institute, ITRI, to evaluate the reliability of HeatCap technology through Dynamic Mechanical Load (DML) and local hot spot tests. HeatCap and reference modules were put through DML tests of 1000 cycles each at 1000 Pa, 2000 Pa, 3000 Pa sequentially, and verified by electroluminescence (EL) pictures. Compared to the reference module, the HeatCap module had significantly less micro-cracks after each stage of DML tests. Local hot spot tests provided evidence of HeatCap's improvement in heat dissipation to reduce the solar cell temperature compared to reference cells. HeatCap can be used to solve the heating issue common to modules with black back sheets, and improve energy outputs of all-black modules in warmer environments.
"PV Taiwan is an opportunity to show the world the health and innovation of the Taiwanese solar industry. With the launch of the micro-crack preventing HeatCap technology, WINAICO continues to be a technology leader and differentiates our product offering with greater reliability to the end customers", said Davis Chen, Chairman and CEO of WINAICO. "The 300 W and 230 W modules on display reinforce WINAICO's position as a producer of PV modules with the best power density, and the leader in Residential solar solutions."

IMO Precision Controls - Keeping Solar Safe

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
